My invention relates to a novel resilient shoe insole and more particularly my invention relates to a novel combination of insole and resilient pad, which combination is adapted to provide increased shoe comfort and al softer, more resilient cushion for the foot and increased breathing and ventilation are effected. A

One of the primary functions of the insole in the shoe is to enable the assembly of the respective components of the shoe, namely upper and outsole, to facilitate the lasting of Vthese parts.

It is the object of my invention to provide that the insole be rendered more flexible, more resient and hence increase foot comfort. G enerally I effect the increased resilience by cutting out an opening in the forepart of the insole and to increase the resilience and softness of the construction I secure over that cut out portion a resilient pad formed; for example, of rubber.

In order that the resilience of lthe assembly be greatest at the center portion and decrease gradually, I provide certain features of the construction which will be more speciiically dealt with hereinafter. For example I may dish out the opening in the insole so that the edgesof the opening are tapered, the taper extending to substantially a feather edge about-the periphery of the opening. I also provide perforations not only through the -resilient pad for purposes of increased ventilation, but additionally in order to provide a graduated resilience, I provide perforations in and through this tapered marginal portion of the insole, these perforations are in line corresponding perforations extending through the resilient pad superimposed and secured thereover. a.

It is the object of my invention to provide a novel resilient combination of insole and 'resilient pad.

It is a further object of my invention to provide a combination of resilient pad and insole with increased flexibility, resilience and ventilating properties.

It is 'a further object of my invention to provide a novel-insole' adapted to provide resilient support of the foot in certain indicated areas.

It is a further object of my invention to im, prove the flexibility and resilience of the shoe insole.

These and further objects of my invention will become apparent from. a consideration of the drawings and the specific description thereof which here follows.

Figure 12 is a central longitudinal cross section of a still further modiiied-form of my invention.

In Figure 1 I show a construction by means of `which I provide increased shoe comfort.4 An outsole I0 and an insole II which has been split from the outsole so that an island or raised portion I2 is provided in the center forepart of the outsole, are joined after the upper I4 is lasted to the insole I I in the usual manner. A resilient pad I5 is secured to the insole II by stitching I6 and I1. I may provide on the resilient pad an integral' metatarsal support I9. The resilient pad I5 is provided with grooves 20 and perforations 2l. Additionally I may provide grooves 23 which communicate upwardly with the interior of the shoe by means of perforations 2l. Where the perforations 2| over lie theinsole II I may fur- 26 in the insole I I by means of which perforations I achieve two new and unexpected results. First, the insole is rendeed more flexible and secondly I provide increased breathing .properties for the shoe'in that vair is circulated througkl;4 the insole and through the resilient pad and ir pockets of increased depth and volume are provided by these perforations 26 in the insole I I.

It is a the resilience and exibility'of the insole gradball portion outwardly towards the periphery. In the center or ball poris a central longitudinal section of a view of a modified form of i y feature of my invention that I increase that point where the lamination of insole and pad rst occurs. These perforations 2| minimize the stiness of the insole so that transition from the middle of the pad I5 to the outer edge of the insole I| is eilected gradually. I may also provide perforations through the insole itself to increase the flexibility thereof. The resilient pad I5 may extend as shown from the toe portion to the longitudinal arch or it may extend from the toe to the heel for the full length of the shoe. The resilient pad and the perforations therein together vwith the perforations in the insole directly below and matching the perforations in the resilient pad have great value for the increased breathing, coolness and flexibility imparted thereby.

In Figures 2 and 3 I show a plan view and cross section respectiyely of the construction described in detail in connection 'with Figure 1. It will be noted that the resilient pad I5 which has its greatest thickness in the central area tapers down to a feather edge as it approaches the marginal portion of the insole IIf.

In Figure 4 I show an insole 30. having a central opening formed therein, the opening being' so cut out asto provide tapered peripheral edge formed from a planular rubber sheet by skiving down the edges thereof to form the tapered edge 34 on the resilient pad 33. This may be effected by skiving out the resilient pad 33 from sheet f orm. For purposes of increased ventilation I provide perforations 35 inthe resilient pad 33 and for increased breathing and ventilation ei!-t fects, I may form in the pad 33, grooves 31 spaced from the perforations 35 and grooves 38 carrying perforations 39 therein'.

It is a feature of this construction that increased softness in the center of the forepart of,

the insole is effected without impairing theI strength o'f the insole or its oonstructional utility in the shoe.'.;: 'I'he resilient pad 33 may be securedA I effect ato the-instale; 30 by the stitching 4|. desirable graduated decrease -of the iiexibility and resilience by providing the tapered edges 34 on the ller 33 and tapered edges 3| on the insole 30, which tapered edges are superimposed over one another. To further enhance this graduated flexibility and resilience I .provide perforations- 43 in this portion of the vinsole where the tapered vedges of the resilient pad-are superimposed over the tapered edges of the insole. The 'insole is adapted to be positioned over the outsole 45. The

resilient pad 33 extends over the insole and terminates in a tapered feather edge 41.

In Figure 6 I show an insole 50 having an opening in the forepart thereof, the opening beingl formed with a tapered edge 5|. edge tapers gradually downwardly to the innermost point in the form of a feather edge. Superimposed over the opening and secured thereto by stitching 52 is a resilient pad 53 containing 55 and combination perforations 54, grooves grooves and perforations 58.

This tapered Formed integrally with the resilient pad is a portion of increased thickness forming the metatarsal 58 which is positioned within the cut out area or at that portion of the-insole that is tapered down to a feather edge. 'Ihis is so that the metatarsal support 58 will be located in a flexible portion of the assembly. In order to provide for the graduated iiexibility and resilience described above, I provide 4for perforations 60 and 6I at that portion where the tapered edges of the insole and resilient pad are superimposed. The resilient pad 53 extends over a substantial area of the forepart of the insole and decreases at its periphery to a feather edge .82. The combination of resilient pad and insole are then properly attached to the outsole 63.

In Figure 8 I show a form of my invention in which the insole is made by splitting off a layer from the outsole and is formed with two openings therein, one opening lying in the center of the forepart and the other lying in the metatarsal region. More speciiically an insole 10 is split oil from an outsole 1I to provide a central opening designated as 12 in the forepart and a secondary opening designated as 13 formed in the region of the metatarsal arch support. Set over the insole 10 and the openings 12 and 13 is a resilient rubber pad 15 carrying an integral metatarsal arch support 16. Perforations 18 extend through the resilient pad and where the resilient pad overlles' the insole 10 perforations 19 extend through both the resilient pad 15 and the insole 10. 'I'he secondary opening 13 increases the exibility of the assembly andalso increases the resilience of the construction. The resilient pad 15 is secured by suitable stitching to the insole 10 and terminates along its periphery in a feather edge 82.

In Figure 10 I show a form of my invention capable of being carried out with great economy and simplicity while at the same time the major objectives of my invention are fulfilled. Thus, an insole is dished ut or cut out to provide a central opening 86 having a downwardly tapering edge 88. 'I'his inwardly and downwardly tapering edge 88 as will be seen increases the flexibility of 'the resilient pad-insole combination and also makes possible-the use of a very simply formed resilient pad 90 which is made by cutting out a rubber sheet to provide the resilient pad 90 and skiving the edges to provide the tapered pad edge 9|. is tapered upwardly and outwardly to iit the tapered edge 88 of the dished out insole.

The resilient pad 90 is perforated centrally to provide perforations 93 and to increase the flexibility of the unit and graduate the flexibility from the central portion outwardly towards the periphery, I provide perforations 94 in that border portion of the combination where the resilient .the combination resilient pad-insole is then 'attached to the outsole 91. 4
